pplcation led September '29, 1899. Serial No. 732,017. (No model.)

To all whom, t may concern.: A

Be it known that I, FRANK ONEILL, a citizen of the United States,residing at Wallaceburg, in the Province of Ontario, Canada, haveinvented new and useful Improvements in Machines for Manufacturing GlassArticles, of which the following is a specification.

The primary object of this invention is to provide a machine of improvedconstruction for manufacturing such glass articles as are partiallyformed by pressingand completed by blowing.

A further object is to improve certain parts of the machine patented tome June 14, 1898, No.605,647,andDecember 20,189,No.616,251.

The invention-consists in the novel features of construction and in thecombination and arrangement of parts hereinafter fully described andclaimed, and illustrated by the accompanying drawings, in which- Figure1 is a front elevation of the machineframe, pressing mechanism, andblowpipe, one of the press-molds and the base of the frame being shownin section. Fig. 2 is a side elevation of the machine, showing a portionof the mold-carrier in vertical section. Fig. 3 is a plan view of themold-carrier, onehalf of the same being shown in dotted lines, the viewincludiin g a sectional plan view of the machine-frame, actuatingmechanism, tbc. Fig. 4 is a vertical sectional View of the blowmold andattending mechanism. Fig. 5 is a detail view of the latch mechanismcarried by the carrier-actuating arm. Fig. 6 is a plan view of a plateor wheel through which intermittent rotation is imparted to the neckmoldcarrier. Fig. 7 is a cross-sectional view, and Fig. 8 a plan view, oftheneck-mold carrier with molds in position; Fig. 9 is a plan view of thecam-plate for opening and closing the neck-molds. Fig. 10 is an enlargeddetail view of the rack and gear for rotating the press-molds. Figs. 11,12, and 13 are detail views of the upper portion of the actuatingmechanism, Fig. 13 being taken on line 00 a; of Fig. 12.

1 is the base, and 2 the upright portion, of the machine-frame.

3 is the drive-shaft; 4, the cams on the shaft; l5, the cross-headcarrying depressor 6, and 7 the pitman vconnecting head 5 and'eams 4.

8 is the plunger-shaft, 9 the plungers arj ranged radially on the shaft,and 10 the ver.` tical side bars depending from shaft Sand operating oncams 4 to reciprocate the plunger-shaft.

The operation and construction of the parte thus far referred' to aresubstantially the same as disclosed in my Patent No. 616,251 and neednot here be more particularly referred to. The mechanism for impartingintermittent rotary motion to the plunger-shaft is, however, animprovement on the corresponding mechanism of my former patents, andconsists of a cogged gear 11 on shaft 8 and operating in conjunctionwith rack 12, slidable horizontally in frame 2. Pin 13 projects from therack into slot 7l of pitman 7, and the rack is thereby reciprocated bythe motion of the pitman. The rack and gear are in engagement (shown inFigs. 1 and 2) and so remain during the succeeding half-revolution ofcams 4. At the same time the pitman is traveling forward and upward inthe direction of the arrow, Fig. 2, and during this move ment rack 12 isadvanced laterally sufficiently to impart one-sixth 'of a revolution togear 11 and shaft 8, bringing a fresh plunger 9 to operative position.The gear and rack then separate by the passage downward of bars 10 overthe abruptly-eu rved sides of cams 4, leaving the rack free for itsreturn reciprocation.

The mold carrier or table 14 is rotatably mounted on post 15, andintermittent motion is imparted thereto forpositioning the molds by arm16, revoluble on post 15 beneath the carrier and carrying at its outerend head 17, in which are the two vertically-reciprocating latches 1Sand 19, held normally raised by springs 18' and 19. The space betweenthe beveled heads of these latches is sufficient to accommodate lugs 2Oon the under side of carrier 14. Arm 16 is oscillated by rod 21, adjustably connected thereto at`21, the rod at its opposite end connectingwith crank 22, secured to the wrist-pin of pitman 7. Rod 2l is jointedoppositely at 23 and 23 to conform to the oscillations vertically andhorizontally of crank 22 and arm 16. Adjustable connection 2l' andturnbuckle 2l of rod 2l afford longitudinal adjustment therefor,wherebyits length may be exactly conformed to the required throw of arm 16.

Latch 18 is what I term the pushing-latch IOO for advancing the table,and when arm 16 is drawn backward for a new hold on the carrier latch 18is automatically depressed bylug 20 and after passing thereunder raisesin engagement therewith and in position for pushing. Latch 19 is for thepurpose of giving actuating-arm 16 a firm hold on the table, preventingthe latter from moving too fast or too far by reason of its ownmomentum. At the end of the advancing stroke the rigidly-supportedfinger 24 enters between nut 19" on bolt 19 and the bottom of head 17,depressing the bolt and freeing arm 16 for the backward oscillation, andsuch oscillation freeing latch 19 from finger 24 the former resumes itsformer projecting position and ready for a new hold.

After carrier 14 has been moved sufficiently to place the molds inoperative position it is locked by the automatic engagement of one oflugs 2O with the depressible latch 25, the forward one of latch-jaws 25'being beveled to permit lug 20 to ride thereover. The latch is heldnormally raised by spring 26. Arm 27 connects the latch with arm 16 andis slotted at 27' to have sliding engagement with pin 25, projectingfrom the latch, the slotted arm sliding on the pin during the greaterpart of the reciprocations of said arm, the arm positively engaging thelatch and depressing it against spring only during the latter part ofits backward movement. The latch is thus lowered and clearot' lug 20, sothat carrier 14 is free to again advance with the advancingreciprocation of arm 16.

The press-molds 28, which are positioned successively over base l andbeneath and in line with the plungers, are removably secured andadjustable vertically in holders 29 by screws 29', each holder beingsecured on the outer end of shaft 30, revoluble in bearings 31 and 32 ontable 14. The shaft is threaded and is moved longitudinally through itsbearings and secured in adjustment by lock-nuts 3l on opposite sides ofbearing 3l. Bearing 32 is slidable radially on the carrier and securedby set-screws 32', whereby the pressmolds may be given such slightradial adjustment as expansion or contraction may render necessary, suchadjustment being insufficient, however, to eramp the shaft in thebearings.

Each shaft 30 carries a gear 33, fiattened at 33 to slide on theuncogged portion of circular rack 34, fixed to post 15. Said rack isformed on its top with cogs 34' of same number as cogs on gear 33, whichwhen reached by gear 33 imparts to the same a complete rotation, thusturning molds 28 for discharging pressed articles, as when the machineis used alone for pressing. Thus the fiat portion 33 of gear 33 is inengagement with the `fiat top surface of rack 34, excepting when thecogs of the rack and gears are in engagement, as above described,thereby holding shafts 30 fixed, with molds 28 in upright or pressingposition.

The blow-molds 35 are arranged on carrier 14 in the circle ofpress-molds 28 and alternating therewith. Each mold 35 is made in twoparts connected on the inner side by hinge 36.

37 is a post raised from carrier 14, and pivoted thereon are the crossedlevers 38, which at their outer ends are connected bylinks 39 toopposite sides of the mold and at their in` ner ends provided with pins40, which depend into continuous double cam-groove 42 ofplate 41. Thisplate is secured to the upper end of shaft 43, journaled vertically inthe carrier, and at the lower end of the shaft is gear 44. Arranged atintervals on the inner periphery of circular rack 34 are cogs 45 and 45.Traversing cogs 45 gear 44 is turned and with it plate 41, thus openingthe mold for removing the completed article. Pins 40 are then in thewidest part of cam-groove 42, and in this position they remain, with themold open, until gear 44 reaches cogs 45', and by traversing same thegear and grooved plate are so turned as to restore pins 40 to thenarrowest part of the groove, with the mold closed. The grooved platenot only operates to open and close the mold, but also holds it rigid inwhatever position the plate may be turned, the fiat portion of gear 44,sliding on the smooth portion of rack 34,also holding the molds inrequisite adjustment.

Each mold 35 opens and closes in an oblong flanged base 46, to whichbottom 35 of the mold is fixed, said bottom having a dovetail edge andthe mold sides dovetail grooves to fit closely therearound.

Extending frontward from the upper part of frame 2 is bracket 47, havingthe vertical socket 48, and movable vertically therethrough is shaft 49,carrying at its upper end the inwardly-extending arm 50, on which isjournaled roller 5l, and this roller plays on the periphery of cam 52 onthe shaft 52', said shaft being actuated by the driving mechanism at thebase of the machine through the medium of the shaft 53 and gears 53.

Shaft 49 hangs suspended over carrier 14 and at the lower end supportthe plate 54, formed with cam-groove 55. Movable vertically with shaft49 and revoluble thereon is the elongated tubular shaft 56, having atits lower end and immediately over plate 54 the neck-mold carrier orwheel 57, formed with oblong openings 58, and hinged at their outersides at 59 in these openings are the divided neck molds or rings 60.The sides of each mold are connected by links 6l to the opposite ends ofthe T-shaped lever 62, fulcrumed to wheel 57. The long arm 62' of thelever moves over curved slot 63 in carrier or wheel 57, and 64 is a pindepending from said arm through slot 63 and into groove 55 of plate 54.With the pin traveling in the concentric part of the groove mold 60remains closed and is opened only when pin 64 traverses offset 55 of thegroove. ,j

Secured to the upper end of tubular shaft IDO Q pressing and blowingoperations and before 56 is plate 65, having a circular series ofapertures 66. y

67 is a lever fulcrumed between its ends at 67'- to frame 2 and at itsupper end is slotted to play on pin 68, carried by cam 52. The lower endof the lever is loosely engaged by arm 69, horizontally rotatable insocket 48. Shaft 49 moves vertically through arm 69 and is splinedthereto at 49', so as to reciprocate therewith when said arm is actuatedby lever 67. Depending from this arm is springbolt 70, which is aboveand adapted to enter successively apertures 66 of plate '65.

7l is the blast or blow pipe, suspended from bracket 72, projectinglaterally from and movable vertically with arm 50, the upper end of thepipe being adapted to receive a lhose (not shown) reaching to a supplyof compressed air. The pipe extends loosely through arm or guide 73,carried by crosshead 5; The pipe is valved at 74, the valve being openedat the downstroke of the crosshead through the medium ofvertically-disposed lever 75, which is pressed outward by the descentofarm 73 and held open thereby until the cross-head rises, which isafter the blowing operation is completed. A spring 76 is interposedbetween valve 74 and arm 73, which is compressed by the latter, holdingthe blowpipe solidly to the mold while emitting the blast.

The operations of pressing and blowing are carried on simultaneously inadjacent molds while mold-carriers 14 and 57 are at rest, the latterbeing in its `lowermost position with adjacent ring-molds 60 closed andresting on adjacent press and blow molds. A batch of glass having beenpreviously placed in the press-mold the plunger descends and presses inneck mold or ring 60 the neck of the jar or other article. At the sametime the next adjacent blow-mold is in position beneath blowj pipe 7land contains the blank pressed by the preceding operation and which issubjected to the blast, thus forming the body of the jar or otherarticle. At the completion of the shafts 49 and 56 begin to rise themotion of lever 67 is reversed, reversing the motion of arm 69, andshaft 49, turning with said arm by reason of spline 47', plate 54 isturned sufficiently to pass pin 64 into offset 55 of groove 55, whichopens ring 60 away from the neck of the article in the blow-mold. Shafts49 and 56 are then raised by the action of cam 52 on roller 5l, raisingwith them the neckmold carrier 57, whereby the blank of glass stillremainingin the neck-mold is lifted out of the press-mold and thepreviously-opened neckmold 60 away from the blown article. Plate 65,rising with the shafts, is engaged at one of its apertures with bolt 70,and at this juncture lever 67 begins its forward reciprocation, andbefore this engagement is broken by lowering of shafts 49 and 56 thelatter have been given one-sixth of a revolution. During this operationthe mold-carrier 14 has also been ad'- vanced one-sixth of a revolution,placing a fresh blow-mold in position to receive the previously-pressedblank, which is lowered thereinto. At the same time a fresh neck mold orring 60 is lowered to position on the fresh press-mold beneath theplunger and the operations of pressing and blowing are repeated. Theaction of the descending crosshead in opening the blast-pipe valve anddepressing said pipe to the mold has been fully explained above, and itwill be understood that this operation occurs simultaneously with theoperation of pressing. As the blowmold moves forward by the advance ofcarrier 14 it is automatically opened and the completed article removed.The blow-moldl is then automatically closed also, as before described,and so remains until ready to discharge another finished article.

' The neck molds or rings and blow-molds are I removable and may bechanged to conform to the work in hand. The plunger-heads andpress-molds may in like manner be varied for different forms ofarticles-as, for instance, tumblers, jelly-glasses, &;c.-capable offormation entirely by pressing.
